The horizontal-bending silicone profile follows gentle plan-view curves and recessed architectural contours. A nominal 11.5 × 21 mm section and 80 mm minimum bend diameter help designers plan compact details without treating the light as a rigid linear fixture. ![Warm white silicone neon flex curving down from an overhead loop against a plain grey wall, the diffused face glowing evenly all the way along the bend](https://static.tpk-led.com/images/website/tpk-led/Product/LNF-SIL-F1220/lnf-sil-f1220-feature-continuous-face-01.webp) ## Soft, uninterrupted light. A continuous diffusing emission face produces a visually smooth linear effect with a nominal 120° beam. Select the LED density and electrical platform for the required run; wattage, segmentation and available white-light options vary by configuration. ![Three warm white runs of silicone neon flex crossing into overlapping loops on a black background, with cut marks and polarity symbols printed along the white extrusion](https://static.tpk-led.com/images/website/tpk-led/Product/LNF-SIL-F1220/lnf-sil-f1220-feature-parallel-runs-01.webp) ## Pixel control, precisely. Available 24V pixel configurations support SPI or DMX control. The 56-LED/m DMX RGBW configuration provides eight addressable pixels per metre and a 125 mm cutting interval. Pixel density varies by configuration; static RGBW is available separately. ![RGB pixel silicone neon flex coiled into a spiral on a dark surface, colours stepping through red, magenta, blue, cyan and green, with the power lead entering from the right](https://static.tpk-led.com/images/website/tpk-led/Product/LNF-SIL-F1220/lnf-sil-f1220-feature-pixel-spiral-01.webp) ## Sealed for architectural use. The silicone construction is specified for IP68-rated factory-sealed assemblies, with a five-year TPK warranty offering. Waterproof performance depends on the completed end seals, electrical connectors and installation conditions—not simply on the uncut extrusion. ![Cut end of a warm white silicone neon flex lying on a wet grey surface, water beaded along the jacket and the internal LED strip exposed at the unsealed end](https://static.tpk-led.com/images/website/tpk-led/Product/LNF-SIL-F1220/lnf-sil-f1220-feature-ip68-wet-end-01.webp) ## Technical specifications.

High-temperature sauna locations require a separately approved fixture and installation design. ![Violet-blue lit parasol canopies on slender poles above a garden path planted with cacti and ornamental grasses at dusk](https://static.tpk-led.com/images/website/tpk-led/Product/LNF-SIL-F1220/lnf-sil-f1220-scene-canopy-parasol-01.webp) ### Sculptural canopies Color-changing outlines support expressive architectural forms and event-oriented lighting schemes where RGB or pixel-control options are specified. ![White ribbon sculpture twisted into a loop on a circular plinth in a city lawn, a warm white light line tracing the ribbon edge and the illuminated base ring](https://static.tpk-led.com/images/website/tpk-led/Product/LNF-SIL-F1220/lnf-sil-f1220-scene-public-art-loop-01.webp) ### Public art accents Flexible luminous contours can follow the geometry of outdoor installations, with electrical configuration chosen for static or dynamic effects. ![Tree-shaped public artwork on a waterfront plaza at dusk, its curved timber ribs crowned with fan-shaped petals outlined in continuous pink and white light](https://static.tpk-led.com/images/website/tpk-led/Product/LNF-SIL-F1220/lnf-sil-f1220-scene-art-tree-01.webp) ### Dynamic installations DMX or SPI pixel platforms can add segmented effects across decorative linear forms, subject to control design and pixel-density selection. ![Warm white neon flex recessed under the nosing of concrete outdoor stairs at a coastal villa in light rain, with a blue-lit pool and glass balustrade alongside](https://static.tpk-led.com/images/website/tpk-led/Product/LNF-SIL-F1220/lnf-sil-f1220-scene-stair-nosing-01.webp) ### Staircase edges Recessed illuminated lines articulate step geometry. Detail the channels, surface exposure and terminations to suit the project. ![Cyan-blue neon flex tracing the curved coping of an infinity pool at a tropical resort at dusk, with a thatched bar lit by warm lanterns behind](https://static.tpk-led.com/images/website/tpk-led/Product/LNF-SIL-F1220/lnf-sil-f1220-scene-pool-coping-01.webp) ### Poolside contours Linear highlights can frame surrounding landscape and pool edges. Submerged use requires confirmation of the complete sealed system and local electrical requirements. ![Amber neon flex running along both edges of a teak yacht foredeck at sunset, with a blue light line under the fascia of the deck above](https://static.tpk-led.com/images/website/tpk-led/Product/LNF-SIL-F1220/lnf-sil-f1220-scene-yacht-deck-01.webp) ### Yacht deck contours A continuous line of light traces deck pathways; verify connector sealing, salt exposure and installation details for each marine project. ## Frequently asked questions. Are standard RGBW and DMX pixel RGBW the same configuration? No. Standard RGBW provides independent red, green, blue and white channels for a common lighting effect across the connected run. DMX pixel configurations add segmented addressing for effects along the strip. The 24V 56-LED/m DMX RGBW configuration provides eight addressable pixels per metre, while other DMX configurations offer different pixel densities.How do voltage and cutting interval affect the selected neon flex? They are linked to the electrical platform, not freely interchangeable options. For example, the 24V 56-LED/m DMX RGBW listing has a 125 mm cutting interval, while a 48V single-color 60-LED/m listing has a 250 mm interval. Select voltage and control first, then confirm the matching cutting interval, wattage and feeding plan.Can the F1220 silicone neon flex be installed in wet outdoor locations? Factory-sealed F1220 assemblies are specified as IP68. Cut ends, cable entries and connectors must maintain the required sealing performance. The stated immersion limit is less than 2 m; pool, marine and high-temperature applications require project-specific compatibility checks. ## Discovery - Site index: [https://www.tpk-led.com/llms.txt](https://www.tpk-led.com/llms.txt) - Section index: [https://www.tpk-led.com/products/llms.txt](https://www.tpk-led.com/products/llms.txt)
